Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.

States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.

Differentiate and validate

Hypothesis: Contractors need faster repeat invoices more than more templates.

First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.

The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.

Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description

BLEASS Sidekick is a combination of a kick drum synth, a step sequencer, and a ducker (aka a sidechain compressor). The result is a plugin that provides a unique way to create exciting rhythmic dynamics within your music. The kick drum synth uses an analogue-style engine inspired by vintage beatboxes, which allows it to create a wide range of classic analogue kick drum tones with ease. This synth can be triggered by the built-in 16-step sequencer or by an external MIDI input; its sound can be mixed with the audio passing through the plugin, be used to trigger the plugin’s ducker stage, or both. Used without the ducker, BLEASS Sidechain makes it easy to add your own kick parts to loops and other percussive parts. Bringing in the ducker causes the input signal to reduce in volume whenever the kick synth is triggered. When used on a drum loop this lets you impose your own creativity on the underlying feel and beat of the loop, ducking-out the loop’s kick sound and pattern so that you can replace them with a sound and pattern that you have crafted. Perhaps BLEASS Sidekick’s best trick, though, is to use the kick synth and sequencer purely as a trigger for the ducker. This lets you create fascinating and detailed dynamic rhythms within any part or track, whether individual instrument or an entire mix. This plugin is AUv3 compatible and offers Multi-Bus output (within AUM) as well as Midi Input. More information and tutorials available on https://www.bleass.com/sidekick

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
